Android Manifest merger failed with Material Date Time Picker

Question

I was trying to add the following library:

https://github.com/wdullaer/MaterialDateTimePicker

After adding the dependency, It is showing me the following error.

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 is also present at [androidx.core:core:1.0.1] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory). Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:7:5-34:19 to override.

I added

tools:replace="android:appComponentFactory"

in the manifest, after adding its showing me following error :

Merging Errors: Error: tools:replace specified at line:8 for attribute android:appComponentFactory, but no new value specified app main manifest (this file), line 7 Error: Validation failed, exiting app main manifest (this file)

I tried to solve it, but no luck. I visited a few similar links also. Please suggest, what should I do to fix this issue?

add as attribute in your tag of `AndroidManifest.xml` `tools:replace="android:appComponentFactory"` — Pratik Butani, Feb 05 '19 at 12:16
i think issue with your `MaterialDateTimePicker` try to downgrade version of `MaterialDateTimePicker` may be latest version is for `androidx` not for `android.support` — AskNilesh, Feb 05 '19 at 12:21

Try both : `tools:replace="android:appComponentFactory" android:appComponentFactory="whateverString"` — Pratik Butani, Feb 05 '19 at 12:24
You can't use AndroidX with Support Libraries. Migrate your project to AndroidX then the issues will be avoided. — Srikar Reddy, Feb 05 '19 at 12:26
@PratikButani That is also not working, to use android:appComponentFactory="whateverString" minSDKVersion should be 28, I made it 28 still it is showing few errors — Shishupal Shakya, Feb 05 '19 at 12:48
@NileshRathod Tried downgrading the library version, still same issue. — Shishupal Shakya, Feb 05 '19 at 12:55
@AndroidDev I had similar problem. By Adding following lines in gradle.properties file: `android.useAndroidX=true android.enableJetifier=true` solved conflicting errors for me. — Brijesh Joshi, Feb 05 '19 at 12:59
@BrijeshJoshi Merger issues gets resolved by adding the lines you suggested, but more errors arises after that. — Shishupal Shakya, Feb 05 '19 at 13:02
@BrijeshJoshi Just had a discussion with its develoer over github, so the issue is resolved by using version 3.6.4 as of 4.0.0 this library is using androidx — Shishupal Shakya, Feb 05 '19 at 13:15
@PratikButani Pls mark this question as not duplicate, since this was not the duplicate of what the links you shared. — Shishupal Shakya, Feb 22 '19 at 08:27
